•White wash: Purdue has done a good job of making White work for his points. The Hawkeyes' senior is shooting 36.8 percent — well below his 51.6 career mark — in five games against the Boilermakers. But White gets to the line an average of eight times per game against Purdue, and he's hitting 83.2 percent of his free throws this season. Can the Boilermakers slow him down without fouling?

•Boarding up: Only one Big Ten Conference teams has a better offensive rebounding percentage than Purdue, and that's Iowa. But the Hawkeyes are the only team in the league with four players averaging at least two offensive boards per game (White, Uthoff, Olaseni and Woodbury). Illinois just beat Purdue largely by feasting on 16 offensive boards. The Boilermakers need, well, a rebound.

•Domino effect: Painter said Friday morning that he didn't know how much Kendall Stephens (finger injury) will play against Iowa, if at all. If he can play in even a limited capacity, his presence is a plus. Purdue's best and highest-volume 3-point shooter stretches the defense and opens driving lanes for Octeus and Davis and passing lanes to get the ball to Hammons and Haas. No other Boilermaker has earned that respect yet. If Stephens can't play, freshmen Edwards and Mathias must add more perimeter scoring punch.
